# Key Points from IRC Log (April 23, 2016)

* Discussion about satellite collision probability computation, with a focus on how secure computation methods could allow adversarial governments to prevent spy satellite collisions without revealing their trajectories, as spy satellites use optical/radar stealth and orbital changes to avoid detection.

* Debate about PCB prototyping methods comparing isolation routing vs chemical etching, with arguments about which is faster, cleaner, and more economical for different circuit complexities and use cases.

* BioViva announced what they claim is the first gene therapy successful against human aging, reporting telomere lengthening from 6.71kb to 7.33kb, though participants expressed skepticism about the "20 years younger" marketing claims.

* Conversation about comparative neurology in dogs, questioning why different sized dog breeds with vastly different brain sizes appear to have similar intelligence levels, with limited scientific literature available on the topic.

* Brief mention of CRISPR technology with a quote from George Church describing it as doing "vandalism" rather than editing, suggesting limitations in its precision.

* Suggestion to fund transhumanist street art as a movement, with examples of DIY bio revolution posters shared.
